Today, I changed the LAG setup to a non-LAG setup and enabled just one of the two ports. Additionally I set every VLAN to tagged. Up to now there are no further problems on the network. Next I'll enable one LAG to see, what is going to happen.

After enabling LAG, the error occurs again. What am I doing wrong?

I came to your post with a different question (trying to stack M4300-8x8f with the S3300-28x) and there's no way the M4300-8x8f will do it unfortunately. M4300-12x12f does however, bummer to find that out after spending money on equipment..
I digress. I see your issue with LAG and stability -- I had similar experiences and issues between the S3300-28x's and different equipment, using and not using vLAN -- there's a proper order to it, I can't say that this is the right order but this is what I recall. LAG then vLAN. If you set it up opposite, it will create flow issues. If you have things NOT DEFAULT before going down LAG then VLAN it will create flow issues. It shows up almost instantaneously in most cases but I've had days where it was fine then it wasn't. I dove through all sorts of documentation to find this tiny footnote and I hope I got it right passing the information to you.Good luck.
